Maybe you can create a “Better Logic” variable of type string for every flow you want to check.
Whenever a flow is executed, you can set the corresponding variable with the date/time converted to a string. This way you can check these variables and see when the flow was executed last.
But this probably is not the best option when you have a lot of flows to be checked.
Use a timer. When the flow is triggert start a timer for the time u want. Every time the flow has triggert the timer whil start again. When the timer is emty the flow has not triggerd whithin the time u wanted. So you made a flow WHEN timer is emty THEN make a notification.
Was hoping there was a simple solution like the system card “a device did not report”
I have several flows that do their work unnoticed (like sending my betterlogic data every night to the “betergas” server.
So If they fail it can go unnoticed for a long time…
